Abstract
The efficiency of automatic repeat quest (ARQ) based transmission protocols decrease due to the high delay and high error rate of deep space communication. Fountain code-based transmission protocols can be adopted to improve the transmission efficiency under such circumstances. In this paper, a central limit theorem was employed to analyze the performance versus error rate of the fountain code-based file delivery protocol. A simulation was conducted in accordance with the probability model of central limit theorem. The result shows that the central limit theorem probability model is close to the actual situation. The central limit theorem can be taken as the principle of protocol design. An expression of packets sent by normal quantile function-based protocol was derived. This expression ensures if the number of packets sent is not less than n, then the successful rate is not less than δ.
